I know there has been issues with AT&T blocking email messages, and that was one of the reasons I could not get voicemail messages on my cell using @mms.att.net, but I always got notification via text message on my phone.

It seems something has changed and as of today I no longer get any messages from Voipo at my @txt.att.net address either. Is this something that changed on Voipo's end, or has AT&T become more aggressive in their blocking of what they consider spam ?
